[0034] The present invention provides a wire welding device. Refer to Figures 1-4 , which includes: a welding torch device 2 for installing a welding torch. The welding torch device 2 includes a pneumatic actuator 3 and a position adjustment assembly 4. The pneumatic actuator 3 is used to push the welding torch close to or away from the welding point. The position adjustment assembly 4 includes a first connecting plate 41, a second connecting plate 42, and a third connecting plate 43; a pneumatic device 1 for providing high-pressure air to the pneumatic actuator 3; a first transmission mechanism is provided between the first connecting plate 41 and the second connecting plate 42, and the first transmission mechanism is used to drive the second connecting plate 42 to reciprocate along a first direction; a second transmission mechanism is provided between the second connecting plate 42 and the third connecting plate 43, and the second transmission mechanism is used to drive the third connecting plate 43 to reciprocate along a second direction; a third transmission mechanism is provided between the third connecting plate 43 and the pneumatic actuator 3, and the third transmission mechanism is used to drive the pneumatic actuator 3 to reciprocate along a third direction.

[0035] Specifically, the pneumatic device 1 and the pneumatic actuator 3 are connected by an air pipe (not shown), so as to provide high-pressure and stable compressed air for the pneumatic actuator 3. The pneumatic device 1 is a device that uses compressed air or gas to achieve mechanical movement and control. It uses compressed air as a power source. The compressed air can be an air compressor or a gas cylinder. The pneumatic device 1 is used to control the downward pressure of the pneumatic actuator 3, which has a high degree of automation and ensures that the downward pressure and lifting of the welding gun are stable, achieving precise pressure control, reducing welding parameter deviations, and improving welding consistency and quality.

[0036] Further, the first connecting plate 41 and the second connecting plate 42 are both rectangular plates, the length direction of the first connecting plate 41 extends along the first direction, the length direction of the second connecting plate 42 extends along the second direction, and the third connecting plate 43 is an L-shaped plate, and the height direction of the side plate of the third connecting plate 43 extends along the third direction. The first direction, the second direction, and the third direction are respectively located in the planes where different coordinate axes in the three-dimensional coordinate system are located. In a specific implementation, the first direction, the second direction, and the third direction are perpendicular to each other, that is, the first direction is the Y-axis direction, the second direction is the X-axis direction, and the third direction is the Z-axis direction.

[0037] Furthermore, the first transmission mechanism, the second transmission mechanism and the third transmission mechanism may adopt the same or different transmission mechanisms, and the transmission mechanisms include but are not limited to belt transmission, guide rail transmission, screw transmission, etc. The transmission mechanism can select the most suitable method according to specific needs. Different transmission mechanisms have their own advantages in terms of force transmission and motion, adjustment accuracy, speed control, etc., so they can be flexibly selected according to different application scenarios. Through the adjustment of the first transmission mechanism, the second connecting plate 42 can be controlled along the first connecting plate 41 to adjust the position of the welding gun in the Y-axis direction, through the adjustment of the second transmission mechanism, the third connecting plate 43 can be controlled along the second connecting plate 42 to adjust the position of the welding gun in the X-axis direction, and through the adjustment of the third transmission mechanism, the pneumatic actuator 3 can be controlled along the third connecting plate 43 to adjust the position of the welding gun in the Z-axis direction. The design of the position adjustment component 4 facilitates the adjustment of the position of the welding gun in three-dimensional space, and can better realize the precise positioning between the welding gun and the welding point, thereby improving the fineness of the adjustment. Among them, the welding point is also called the welding position, which refers to the spatial position of the joint of the two steel wire weldments during welding.

[0038] In this embodiment, see Figures 3-4 The pneumatic actuator 3 includes but is not limited to a cylinder and a pneumatic motor, and a mounting portion 31 for mounting a welding gun is provided on the pneumatic actuator 3. The mounting portion 31 is rotatably provided at the driving end of the pneumatic actuator 3, and the side of the pneumatic actuator 3 that is away from the mounting portion 31 is connected to the third slider 32 through a mounting plate.

[0039] Specifically, the pneumatic actuator 3 is used to convert the energy of the high-pressure gas provided by the pneumatic device 1 into mechanical motion to complete the pushing and pulling operations, thereby precisely controlling the lifting height of the welding torch. In a specific implementation, the pneumatic actuator 3 is a cylinder, and a cylindrical piston that moves linearly in the cylinder is provided on the cylinder. High-pressure air from the pneumatic device 1 is transmitted through an air pipe, thereby guiding the piston on the cylinder to move, and then driving the push block connected to one side of the piston to move, so as to realize the control of the downward pressure and lifting of the welding torch during the welding process.

[0040] Further, the mounting portion 31 is a rotatable slot-type connection joint. The welding torch can be fixed to the pneumatic actuator 3 through the mounting portion 31 and is allowed to be rotationally adjusted when needed to adapt to different welding angle and position requirements, which makes the welding operation more convenient and flexible. The rotation principle of the mounting portion 31 is through an arc-shaped slot (not marked) opened above it, and corresponding hole positions (not marked) corresponding to the arc-shaped slot are provided on the pneumatic actuator 3. The connection between the two is achieved by passing a connecting piece such as a screw through the arc-shaped slot and the hole position. Just loosen the screw to make the mounting portion 31 rotate relative to the pneumatic actuator 3.

[0041] In this embodiment, referring to Figures 3-4 , the first transmission mechanism includes a first guide groove 411, a first slider 421 slidably disposed on the first guide groove 411, and a first lead screw 44 drivingly connected to the first slider 421; the second transmission mechanism includes a second guide groove 422, a second slider 431 slidably disposed on the second guide groove 422, and a second lead screw 45 drivingly connected to the second slider 431; the third transmission mechanism includes a third guide groove 432, a third slider 32 slidably disposed on the third guide groove 432, and a third lead screw 46 drivingly connected to the third slider 32.

[0042] Specifically, the transmission mechanism adopts a lead screw transmission. The first lead screw 44, the second lead screw 45, and the third lead screw 46 are long rods with a threaded structure. The three lead screws are respectively drivingly connected to the respective connecting parts through corresponding couplings (not shown), and the couplings that cooperate with the threaded structure are respectively located in the first guide groove 411, the second guide groove 422, and the third guide groove 432. When the corresponding lead screw is rotated, the threads of the screw and the nut engage with each other, causing the nut to move along the axis direction of the lead screw. Thus, the input rotational motion is converted into an output linear motion through the cooperation of the threads of the lead screw and the nut. Through the cooperation of the lead screw and the coupling, force and motion are transmitted between several connecting plates, the first bracket, and the second bracket to realize the relative horizontal motion between them pairwise.

[0043] In a specific implementation, the first slider 421, the second slider 431, and the third slider 32 are respectively provided with avoidance grooves 47 for the first lead screw 44, the second lead screw 45, and the third lead screw 46 to pass through.

[0044] The following further illustrates this embodiment by examples. However, the following examples are merely illustrative and should not be considered as limiting the scope of the present invention. Obviously, those skilled in the art can make any changes, improvements, or modifications without departing from the spirit of the present invention.

[0045] See Figures 1-4 An example of the present invention: The first guiding groove 411 is formed on the first connecting plate 41. The first slider 421 is a slider formed by extending one side of the second connecting plate 42. When the second connecting plate 42 reciprocates in the first direction, a certain guiding effect can be achieved through the horizontal sliding between the first slider 421 and the first guiding groove 411. Further, the first slider 421 is provided with an avoidance groove 47 for avoidance for the first lead screw 44 to pass through. The first lead screw 44 is rotatably arranged around its own axis on the first guiding groove 411, and a coupling is provided between the first lead screw 44 and the second connecting plate 42. At the same time, bearings are also provided at the ends of the lead screw to obtain certain support and guidance in its length direction, ensuring the stability and motion accuracy of the lead screw. The rotation of the first lead screw 44 can be realized by manual control or connected to a driving mechanism. When the first lead screw 44 is rotated, the rotary motion is converted into a linear motion under the transmission of the coupling, thereby driving the second connecting plate 42 to reciprocate in the first direction;

[0046] The second guiding groove 422 is formed on the second connecting plate 42. The second slider 431 is a slider formed by extending the bottom of the third connecting plate 43. When the third connecting plate 43 reciprocates in the second direction, a guiding effect can be achieved through the horizontal sliding between the second slider 431 and the second guiding groove 422. Further, the second slider 431 is provided with an avoidance groove 47 for avoidance for the second lead screw 45 to pass through. The second lead screw 45 is rotatably arranged around its own axis on the second guiding groove 422, and a coupling is provided between the second lead screw 45 and the third connecting plate 43. At the same time, bearings are also provided at the ends of the lead screw to obtain certain support and guidance in its length direction, ensuring the stability and motion accuracy of the lead screw. The rotation of the second lead screw 45 can be realized by manual control or connected to a driving mechanism. When the second lead screw 45 is rotated, the rotary motion is converted into a linear motion under the transmission of the coupling, thereby driving the third connecting plate 43 to reciprocate in the second direction;

[0047] The third guiding groove 432 is formed on the side plate of the third connecting plate 43. The third slider 32 is a slider formed by extending from one side of the pneumatic actuator 3. When the pneumatic actuator 3 reciprocates in the third direction, a certain guiding effect can be achieved through the horizontal sliding between the third slider 32 and the third guiding groove 432. Further, an avoidance groove 47 for avoidance is provided on the third slider 32 for the third lead screw 46 to pass through. The third lead screw 46 is rotatably arranged around its own axis on the third guiding groove 432, and a coupling is provided between the third lead screw 46 and the pneumatic actuator 3. At the same time, bearings are also provided at the ends of the lead screw to obtain certain support and guidance in its length direction, ensuring the stability and motion accuracy of the lead screw. The rotation of the third lead screw 46 can be realized by manual operation or connected to a driving mechanism. When the third lead screw 46 is rotated, the rotary motion is converted into a linear motion under the transmission of the coupling, thereby driving the pneumatic actuator 3 to reciprocate in the third direction.

[0048] In this embodiment, referring to Figures 3-4 , the first guiding groove 411, the second guiding groove 422 and the third guiding groove 432 are all arranged as trapezoidal grooves, and the first slider 421, the second slider 431 and the third slider 32 are respectively adapted to the corresponding trapezoidal grooves. The two sides of the trapezoidal groove have inclined surfaces, which are matched with the shapes of the corresponding connecting parts, so as to ensure good positioning and guidance during the movement process, thereby improving the accuracy and stability of the system. At the same time, due to the special shape of the trapezoidal groove, compared with other guiding structures (such as linear grooves), the wear between components can be adjusted, which helps to extend the service life of the equipment, and the matching of the shapes can also simplify the assembly and adjustment process.

[0049] In this embodiment, referring to Figures 3-4 , the position adjusting assembly 4 further includes a plurality of adjusting knobs 48 respectively used for rotating the first lead screw 44, the second lead screw 45 and the third lead screw 46. The plurality of adjusting knobs 48 are respectively arranged at one end of the first lead screw 44, the second lead screw 45 and the third lead screw 46. Due to the adoption of the adjusting knobs 48, the user can freely rotate the corresponding lead screw according to needs, so as to facilitate controlling the adjustment of the welding torch device 2 in different directions in the three-dimensional space by each transmission mechanism, and realizing the flexible control of the position adjusting assembly 4.

[0050] In this embodiment, referring to Figures 1-2, the wire welding equipment further includes a fixing device 5 for fixing the wire, and the fixing device 5 includes a quick clamp 51 and a positioning part 52. Among them, the quick clamp 51 is a device for clamping the wire, and it has the functions of quick clamping and releasing. The positioning part 52 is a component for ensuring that the wire maintains the correct position during the welding process, which is achieved by opening a positioning hole on the positioning part 52. By passing the clamped wire through the positioning hole, the wire can be prevented from shifting or shaking during the welding process, so as to obtain high-quality welding results. When welding the wire, first, the operator can loosen the quick clamp 51. When the quick clamp 51 is loosened, it is used to open the positioning hole on the positioning part 52. The operator can bring the two wires together and extend them into the opened positioning hole, and then operate the quick clamp 51 to close the positioning hole to clamp and fix the two together wires, effectively improving the efficiency of fixing the wire and enabling the wires to be welded to effectively maintain the consistency of the fixed position during wire welding, thereby improving the precision of wire welding.
